This species was quite common in September. I am not absolutely sure that this is a Tachinid.

Looks like a Voriini (down-curved bristles on the face + strongly angled m-cu) - possibly
Voria ruralis :) Hairs on r4+5 beyond r-m would suggest
Athrycia but I can't see hairs along the veins. Theo might have other alternatives too of course :D

Thx Chris, I think this will be Voria ruralis. The three paris of long bristles on the top of the head together with the very oblique crossvein in relation to m should be sufficient to id this to species. But Theo will confirm or refute.
Is it possible to sex the flies on the images?

Sexing is tricky. I know some groups can be sexed using the numbers of proclinate or reclinate bristles on the parafrontal. But I'm not sure if that's the case with Voriini. I am usually dealing with specimens so I can always turn them over and examine the tip of the abdomen :D
I probably should have said it better but
Athrycia also has downcurved facial bristles and an strongly angled m-cu ... but in addition they have the hairs along r4+5 beyond r-m (I think, off the top of my head!) ;)

Chris is right with Voria ruralis and sexing is tricky in Voriini: look at the length of the claws.
These are short, so this is a female
